LEDs for external connectors count from the bottom up (e.g. bottom LED is for top connector).
LED Meaning Description
1 On=100Mb Off=10Mb Internal RJ-45 Connector to CAC3
2 External Top RJ-45 Connector
3 External Second RJ-45 Connector
4 External Third RJ-45 Connector
5 External Bottom RJ-45 Connector

Ethernet Switch Board with Fiber (ESBF)
The Ethernet Switch Board with Fiber (ESBF) is similar to the Ethernet Switch Board (ESB)
described previously. The primary difference is that for the ESBF one of the 10/100Base-T
connectors has been replaced with a 100Base-FX 1300 nm fiber optic connection with duplex
ST® connectors. This fiber connection is not compatible with 10 megabit fiber systems.
As can be seen in Figure 2-22 on the following page, the ESBF is equipped with two edge
connectors, one on the top of the board and one on the bottom. The board is designed in this
manner to support its use in either the network slot (slot 5) of a SYSCON2.1 or in a PCI slot
of a SYSCON2.1 or legacy SYSCON1. The slot edge connectors are labeled on the board as
“SYSCON2.1 NETWORK SLOT” and “SYSCON/PCI SLOT”. Only one Ethernet Switch may
be used in an analyzer for external Ethernet communication.
However, It is possible to use an ESB in slot 5 for external Ethernet, and an ESBF in another
slot in the alternate configuration for internal Ethernet in cases where legacy SNECON
modules must be used.
